Thanks for the tips! I'll try that tommorrow when I finish my neighbours drive. You could be right about snow getting in the cup as the drifts were as high as the machine in some parts. I noticed the problem begins to develop if I do a deep pass with the carb side of the machine in on the side of the snow drift.
I have a few commerical user friend with the 3650 that has had similar freeze up problems -so much so that he is selling his 3650. It gets pretty cold here -20-40C range so it is harsh on the machines.
Thanks again
The magical -40C where -40C equals -40F.
By anyone's measure that is pretty cold.
I wouldn't want to be running for more than 20 minutes in that temperature.
I have never had the misfortune to run any of my machines colder than 0F (-18C). At your temperature maybe freezing condensate from the engine exhaust is also a problem but you are in territory where I am just guessing. Since you are talking centigrade maybe some of our Canadian members can be of some help.
